Publication number: 20140117077Abstract: A method for identifying assets is provided. The method includes illuminating an identification pattern associated with the asset with non-visible light. The identification pattern includes retroreflective material that represents identity information of the asset. The method further includes adjusting either a shutter speed of an image sensor, or a power of the non-visible light, or both, based on motion state of the asset. The image sensor is configured to receive response of the retroreflective material to the non-visible light. Furthermore, the method includes the step of identifying the asset based on decoded identity information. The decoded identity information is obtained by processing the response of the retroreflective material.Type: ApplicationFiled: October 30, 2012Publication date: May 1, 2014Applicant: GENERAL ELECTRIC COMPANYInventors: Donald Wagner Hamilton, Peter Henry Tu, Ting Yu, Yi Yao, Dashan Gao

Publication number: 20130243309Abstract: A system and method for estimating a set of landmarks for a large image ensemble employs only a small number of manually labeled images from the ensemble and avoids labor-intensive and error-prone object detection, tracking and alignment learning task limitations associated with manual image labeling techniques. A semi-supervised least squares congealing approach is employed to minimize an objective function defined on both labeled and unlabeled images. A shape model is learned on-line to constrain the landmark configuration. A partitioning strategy allows coarse-to-fine landmark estimation.Type: ApplicationFiled: May 10, 2013Publication date: September 19, 2013Applicant: NBCUniversal Media, LLCInventors: Yan Tong, Xiaoming Liu, Jilin Tu, Peter Henry Tu, Frederick Wilson Wheeler

Publication number: 20130114942Abstract: A novel technique for performing video matting, which is built upon a proposed image matting algorithm that is fully automatic is disclosed. The disclosed methods utilize a PCA-based shape model as a prior for guiding the matting process, so that manual interactions required by most existing image matting methods are unnecessary. By applying the image matting algorithm to these foreground windows, on a per frame basis, a fully automated video matting process is attainable. The process of aligning the shape model with the object is simultaneously optimized based on a quadratic cost function.Type: ApplicationFiled: November 7, 2011Publication date: May 9, 2013Applicant: General Electric CompanyInventors: Ting Yu, Peter Henry Tu, Xiaoming Liu, Ser Nam Lim
